Assistance animal practice exists at the intersection of human health, animal welfare and the environments in which people and animals live and work.

A traditional approach may focus primarily on whether an assistance animal can perform required tasks.

However, contemporary practice recognises that successful assistance animal partnerships depend on a much broader understanding of wellbeing.

The One Health approach recognises that:

• human health;
• animal health;
• environmental health;

are interconnected.

A change in one area can affect the others.

For example:

• An unhealthy assistance animal may be unable to work safely, affecting the person’s independence.
• An unsupported handler may struggle to maintain the animal’s wellbeing.
• An unsuitable environment may create stress for both the person and animal.

One Health and holistic human–animal wellbeing approaches encourage professionals to consider the entire system surrounding the assistance animal partnership.

The focus shifts from:

“Can this animal perform the required tasks?”

towards:

“How can we support the long-term health, wellbeing and sustainability of this human–animal partnership within its environment?”

Understanding the One Health Approach

One Health is based on the understanding that humans, animals and the environment are deeply connected.

Historically, human health, veterinary care and environmental management have often been considered separate fields.

One Health recognises that effective solutions require collaboration between these areas.

Within assistance animal practice, this means considering:

Human wellbeing

Including:

• physical health;
• mental health;
• disability support needs;
• participation;
• independence;
• quality of life.

Animal wellbeing

Including:

• physical health;
• emotional welfare;
• nutrition;
• enrichment;
• workload;
• rest;
• retirement planning.

Environmental wellbeing

Including:

• safe access;
• public health;
• environmental sustainability;
• community acceptance;
• impact on other animals and ecosystems.

Moving Beyond a Task-Only Approach

A common mistake in assistance animal practice is measuring success only through task performance.

For example:

“The dog performs three trained tasks, therefore the partnership is successful.”

While trained tasks are important, they are only one part of a successful partnership.

A holistic approach also considers:

• Is the animal healthy?
• Is the animal comfortable?
• Does the person feel supported?
• Is the workload sustainable?
• Does the environment support the partnership?
• Are both members of the team thriving?

A dog may perform tasks reliably but still experience:

• stress;
• discomfort;
• fatigue;
• inadequate enrichment.

Likewise, a person may have a technically trained assistance animal but not experience meaningful improvement if the partnership does not fit their lifestyle.

Human Wellbeing Within the Assistance Animal Partnership

Assistance animals exist to support people with disability.

Therefore, human wellbeing remains central.

Potential benefits may include:

• increased independence;
• improved confidence;
• greater community participation;
• increased routine;
• reduced barriers;
• improved quality of life.

However, professionals must avoid suggesting that assistance animals are a replacement for all other supports.

A holistic approach recognises that people may also benefit from:

• healthcare;
• therapy;
• social supports;
• workplace adjustments;
• accessible environments;
• community connections.

The assistance animal is part of a broader wellbeing system.

Animal Wellbeing Within Assistance Animal Practice

Animal welfare is not an optional consideration.

An assistance animal is a working partner, but it remains an animal with needs beyond its role.

Animal wellbeing includes:

Physical health

Including:

• veterinary care;
• preventative healthcare;
• appropriate nutrition;
• pain management;
• injury prevention.

Behavioural wellbeing

Including:

• appropriate training;
• confidence;
• enrichment;
• opportunities for normal behaviours.

Emotional wellbeing

Including:

• feeling safe;
• manageable stress levels;
• positive relationships;
• appropriate rest.

A successful assistance animal program must protect the animal’s quality of life.

The Importance of Preventative Healthcare

One Health principles highlight the importance of prevention rather than only responding when problems occur.

For assistance animals, this includes:

• regular veterinary checks;
• vaccination;
• parasite prevention;
• dental care;
• appropriate grooming;
• monitoring changes in behaviour or performance.

Behaviour changes may sometimes be the first indication of:

• pain;
• illness;
• stress;
• ageing.

For example:

An assistance dog that suddenly becomes reluctant to enter busy environments may not be “losing training”.

It may be experiencing:

• discomfort;
• anxiety;
• fatigue;
• a health problem.

A holistic approach investigates the underlying cause.

Environmental Considerations

The environment plays a significant role in human–animal wellbeing.

An environment that is suitable for one partnership may not be suitable for another.

Considerations include:

• housing;
• workplace;
• climate;
• transport;
• community environments;
• access to outdoor spaces.

For example:

A highly active young dog may struggle in a lifestyle with limited opportunities for movement and enrichment.

A calm older dog may thrive in a quieter environment.

The right match considers the whole environment, not only the person’s disability-related needs.

Infectious Disease and Public Health Considerations

One Health principles are particularly relevant to infectious disease management.

Assistance animals interact with:

• humans;
• other animals;
• public spaces.

Therefore, responsible practice considers:

• vaccination;
• hygiene;
• parasite prevention;
• infection control;
• appropriate management when animals are unwell.

This protects:

• the assistance animal;
• the handler;
• other animals;
• the community.

For example:

An assistance animal experiencing an infectious illness may need temporary restrictions to protect others.

This does not remove the animal’s status as an assistance animal.

It reflects responsible health management.

The Environment and Other Animals

Holistic practice recognises that assistance animals exist within shared ecosystems.

Considerations may include:

• wildlife protection;
• livestock safety;
• other assistance animals;
• companion animals;
• community environments.

For example:

An assistance dog may have access rights to a national park, but responsible handling includes:

• remaining on established pathways;
• preventing disturbance to wildlife;
• managing toileting appropriately;
• following environmental requirements.

Access and environmental responsibility can exist together.

The Human–Animal Relationship as a Health Partnership

The human–animal bond itself can contribute to wellbeing.

Assistance animals may provide:

• companionship;
• routine;
• motivation;
• connection;
• emotional support.

However, professionals should recognise that the relationship must benefit both parties.

The animal should not be valued only for what it provides.

The animal’s own wellbeing is part of the success of the partnership.

Example: An Assistance Dog Showing Behaviour Changes

An assistance dog that has worked reliably for several years begins:

• avoiding tasks;
• becoming slower;
• appearing distracted.

A task-focused approach may assume:

“The dog needs more training.”

A One Health approach considers:

• Is the dog experiencing pain?
• Has the environment changed?
• Is the workload appropriate?
• Is the dog ageing?
• Are there health concerns?

The solution may involve:

• veterinary assessment;
• workload changes;
• environmental adjustments;
• retirement planning.

Example: Matching an Assistance Animal to Lifestyle

A person wants an assistance dog and lives in a small apartment.

A simplistic approach may focus only on:

“Can the dog perform the tasks?”

A holistic approach considers:

• the dog’s exercise needs;
• enrichment opportunities;
• the person’s routine;
• available supports;
• environmental suitability.

A large dog is not automatically unsuitable.

A small dog is not automatically suitable.

The focus is the complete human–animal–environment system.

One Health and Assistance Animal Professionals

Professionals should recognise that assistance animal practice requires collaboration across disciplines.

This may include:

• occupational therapists;
• veterinarians;
• trainers;
• behaviour professionals;
• disability professionals;
• healthcare providers;
• environmental professionals.

No single profession holds all the knowledge required.

Collaborative practice improves outcomes for:

• people;
• animals;
• communities.

The Role of Ethical Decision-Making

One Health encourages professionals to consider competing needs.

Sometimes decisions involve balancing:

• human benefit;
• animal welfare;
• public safety;
• environmental protection.

For example:

An assistance dog may legally be able to enter an area, but the environment may create unacceptable risk for the animal or other species.

Ethical practice considers all factors rather than focusing on one interest alone.

Key Practice Principle

One Health and holistic human–animal wellbeing approaches recognise that assistance animal partnerships exist within a larger system.

A successful partnership requires:

healthy people + healthy animals + supportive environments.

The goal is not simply:

“Can this animal complete the required tasks?”

The goal is:

“Can this human–animal partnership remain healthy, ethical and sustainable over time?”

A truly professional assistance animal sector recognises that supporting the person also means supporting the animal, the relationship and the environment in which they live and work.
